Speciiication forming part of Letters Patent No. 115,350, dated May 301871.

To all whom it may camera:l

Be it known that I, GEORGE T. PARRY, o

the city and county of Philadelphia, in the i State of Pennsylvania,have invented a new ,and ImprovedVapor-B urner; and I do hereby declarethat the following is a full, clear, and

exactdescription thereof, reference being had to the accompanyingdrawing making part of this specification, in which- Figure 1 is a diametricalsection through the improved burner. Fig. 2 is a sideview of the .brnenFig. 3 is a horizontal 'section through the cone top taken above theperfora-ted diaphragm therein. t l

Similar letters of reference indicate corresponding partsin the severalfigures.

This inventionrelates to burners which are designed for burning the`vapors ofv light hydrocarbon fluid. The nature Yofmy invention consistsin the combination of a vertically-adjustable burner-tube, a stationaryinternal stem, and regulating-valves, whereby the ow of the iiuid intothe burner can be nicely regulated, or, if desired, entirely cut oli',as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I willdescribe its construction and operation.

In the accompanying drawing, A represents the burner-tube, which isbeveled on its lower end, screw-threaded, and fitted into an elbow, D.This elbow has a small aperture, t, leading into its verticalportion,and at s s is a` seat for receiving the lower beveled end of tube A whenit is desired to cut off the ow of burning-fluid intothis tube. The tubeA isl verticallyadjustabla and, at the upper end of its elbow D, it isprovided withua packing-box l `or cap, g, shown in Fig. l. The upper endof thetube A enters and is secured tightly into an inverted conicalfrustum, B, which has sei curedinto it, on thepupper terminus of saidtube, a horizontal perforated diaphragm, h.

lBeneaththe frustnm B the external surface of the tube A isscrew-threaded, and on this screw-threaded portion an adjustable collar,C, is applied andused for closing or partially `closing orifices om.lising from the elbowD through the center of the tube A, and permanentlysecured to said elbow, is a stem, G, which terminates at a point justbelow the air- `inlets a a in a conical valve, s', which is adapted to avalve-seat, n, in tube A. All that portion of the burner above thevalve-seat n forms a vapor-receptacle; and all that portion vof the tubeA below the valve-seat receives the stem G and a porous packing, whichlatter will cause the ascent of uid through valve-open r ing n into thevapor-receptacle, where it is volatilized and burned'at the apertures bb.

To light the burner the tube A is slightly u rotated about its axis,which causes it to rise and open the valves above and below, and thusform acommunication between the vaporchamber above the valve-seat n andthe fluid below it. A light is then applied to the frustum, and when thevapor therein` is sufficiently expanded it will issue from the aperturesb b and ignite. The heat which is now generated by the burnerfjets willcontinue to volatilize the iluid and keep up a constant supply of vapor.The collar Gis adjustable for allowing more or less air to enter thevaporizing-chamber and mix with the vapor therein. The tube A isadjustable for regulating the iiow of fluid into the burner or forentirely closing the inlet-passage t.. The perforated diaphragm h on topof the tubeA allows the vapor to pass up and then n own through it. Thisdiaphragm becomes h' ly heated, and assists in the rapid conversion ofthe vapor into gas; and when the light is extinguished the diaphragmwill retain for a long time its heat, which will generate gas in thefrustum and render the burner easily relighted.y j

Havin g described my invention, what I claim 1s- The adjustableburner-stem A, the stationary ysolid valve-stem G, `and the valve andvalve-seats n s, combined to operate substantially as described.
